Macintosh users:Space and Earth Update are primary programmed on
Macs, and it is strongly recommended using Macs for your display computers. At a
minimum, you need a Mac Power PC with 64 MB free RAM, CD player, System 8.1 or
higher with Quicktime 4 or higher installed. The software runs much faster and
allows one-click updating of today's latest images if you copy the software
suite to your hard drive. In that case, please note the total hard disk
requirements below for installing all the software on your computer instead of
running it from the CD.

SPACE UPDATE
You need 450 MB of free hard disk space for all of SPACE UPDATE, or 50-140 MB
free if you only wish to show one of the modules (Sky Tonight is the largest
because of the skyview movies included). Monitor requirements are 640x480
pixels, with 16-bit color (thousands of colors). No keyboard is necessary for
the display - only a trackball or trackpad and clicker.

EARTH UPDATE
You need 300 MB of free hard disk space for all of EARTH UPDATE, or 20-80 MB
free if you only wish to install one of the spheres. Monitor requirements are
800x600 pixels, with 16-bit color (thousands of colors). No keyboard is
necessary for the display - only a trackball or trackpad and clicker.

Windows users:Space Update will run on Windows 95, 98, NT, 2000,
and ME, with at least 64 MB of RAM. Sound cards are necessary to hear the
effects (but are not necessary for module operation). You need 400 MB free hard
disk space for all of SPACE UPDATE; or 50-140 MB if you only wish to show one of
the modules. The Windows versions requires Quicktime 4, and a display set to
High Color (16 bit). The Windows version is not available in two-screen format.

2 Screen version:Our two-screen version is only available for Mac's.
The first monitor is the typical "Space Update" screen. The second
monitor displays the chosen image in highest resolution, without menu buttons or
text shown - perfect for putting on a projector for a live lecture. The second
screen has a resolution of 640x480 pixels for Astronomy, Space Weather, and
Solar System. It is also possible to display the second screen on an RGB
projection system, or TV monitor depending on your setup and video capabilities.
The two-screen version CD contains both the individual two-screen modules and
the 16-bit color version of the single-screen Space Update program - basically
everything which is presently on display at the Houston Museum of Natural
Science!
